How to Restore Weathered Cedar Wood Using Cedar Wash
Cedar is one of the most beautiful and durable woods used in outdoor structures — but even the toughest cedar weathers over time. If your cedar deck, fence, or siding has turned gray, grown mildew, or lost its natural luster, Safe Structures Cedar Wash can bring it back to life.
Why Cedar Weathers
Cedar contains natural oils that protect it from moisture and insects, but prolonged exposure to UV rays, rain, and humidity breaks down those oils. The result: a dull, gray surface covered in dirt, algae, and mildew. Left untreated, weathered cedar can crack, splinter, and deteriorate — costing you far more in repairs or replacement than a simple cleaning would.
What Is Safe Structures Cedar Wash?
Safe Structures Cedar Wash is a professional-grade cleaning solution formulated specifically for cedar and other exterior wood surfaces. Unlike harsh bleach-based cleaners that strip wood fibers and damage the grain, Cedar Wash uses a targeted formula to lift dirt, mildew, and algae stains while preserving the wood's natural texture and integrity.
Each case includes two 20lb pails — enough product to tackle large-scale restoration projects on decks, fences, siding, and more. Browse our full Cleaning Products collection for more professional-grade solutions.
Step-by-Step: How to Restore Cedar with Cedar Wash
- Prepare the surface: Remove furniture, planters, and any items from the cedar surface. Sweep away loose debris.
- Mix the solution: Follow the label directions to dilute Cedar Wash to the appropriate concentration for your level of soiling.
- Apply evenly: Use a pump sprayer or brush to apply Cedar Wash across the entire surface. Work in sections to prevent the solution from drying before you rinse.
- Allow dwell time: Let the solution sit for the recommended time so it can penetrate and lift stains.
- Rinse thoroughly: Use a garden hose or low-pressure washer to rinse the surface clean. Avoid high-pressure settings that can damage wood fibers.
- Inspect and repeat if needed: For heavily stained surfaces, a second application may be necessary.
- Allow to dry completely: Before applying any stain or sealer, ensure the cedar is fully dry — typically 48–72 hours depending on conditions. See our guide on how to prep cedar before staining for the full process.
Pro Tips for Best Results
- Apply on a cloudy day or in the shade to prevent the solution from drying too quickly.
